Hi. My Fluval 405 just died for no reason after 22 months , so I just did a 25% water change.

How long can I go without filtration until I can get a new filter shipped to me?

55 Gallon Freshwater

2 Silver Dollar

5 Cichlids

1 Guorami

1 giant tetra

Thanks.

Do you happen to have lots of lava rock in the tank?

I'm still new so my advice may not be on par, but I put lava rock as decor throughout my tanks so there can always be extra bio-filtration in the tank, at least thats what I assume it would end up doing.

Either way from my little knowledge, it would seem that if the shipping is only a week, the tank should be fine if it's established if you do like a 20% every 2 days or something along those lines.

But again, I'm not experienced, this would just be my thoughts if it happened to me.
